Hello,
How long max input string could Bison support? 4K? 2K? or 1K? I met one issue when use bison to parse a long digitMap (length is 4096 characters), which is used for voip digitMap, looks like: ([2-8]xxxxxx|13xxxxxxxxx|1800383848|0xxxxxxxx|9xxxx|*|#|x.#|1[0124-9]x|[0-9*#].T..................................................... I did not get any error from yyerror, e.g. syntax nor memory exhausted. but from high level SW which used Bison, I could see count of memory free is more than memory allocation so "mem error " reported. Thank you if you could provide some clues. Br Lewis
